Cylinder surface finish can make or break an engine build. Proper honing creates the geometry and texture piston rings need to seat, seal, control oil, and last. It’s not just about making a bore smooth—it’s about creating the right surface.

Some shops send blocks out for reconditioning without the ability to verify the work afterward. That can lead to costly problems. At LN Engineering, every block and cylinder is extensively inspected so you don’t have to.

As Cayenne, Macan, and Panamera models with Alusil engine blocks get up there in age, some of the flaws in their construction are showing. Many don't realize bore scoring even is a thing, so they don't know that they need to take action to prevent it.

It's not everyday that we get to see a double whammy! As the piston slaps around due to increased clearances caused by bore scoring, the chances of a d-chunk failure increase. Keep that in mind before you drive your engine to death!

Wix oil filters are recommended for all Porsche engines fitted with our spin on oil filter adapters. When stocking up for that next oil change, don't forget to also get a SPEEDiagnostix kit to test your used engine oil!

If you haven't changed your Porsche's gear oil lately, what are you waiting for?

The EA839 2.9T and 3.0T V6 found in Audi and Porsche models might not suffer from what we consider traditional bore scoring, but bank 2 major thrust side are having problems with piston skirt wear. We're sure the factory 0w20 fill doesn't help! Time for some Driven DI40!
